vented Apparatus for the Separating of Solid Bodies from Liquids byCooling; and

We do hereby declare the followingto be full, clear, and exactdescription. oi the invention, such as wlll enable others skilled in theart to which 1t appertains to ma and use the same, reference being hadto the :LGCOUP panyirlg drawings, and to numerals ol rel'ercnce markedthereon, Which form a part ol' 1 cooling and consequent separation.

this specification.

This invention relates to a cooling process tor the separation of SOl1(lbodies in which they are dlssolved, such, for example, as paraffin, from.paraliin oil and to apparatus for cooling the liquid for effecting; theseparation.

The process consists in cooling the body of the liquid by a suitablenumber of cooling bodies arranged in proximity to one another, incontinuously removing the solids deposited upon the Walls or surfacesthereof by means of agitators, such as scrapii'ig or stiri ringmechanisms and in conveying tbbm' away from the vessel.

In cooling apparatus as heretofore used for this purpose, the paratlinoil or the like to be cooled is introduced into a vessel the Wall ofwhich is cooled by fluid which circulates in 40 that the oil is held inan annular space the outer and imier wells of which are cooled. Suchapparatus possesses, novvevcr, the d1s advantage that the coolingsurface is small relativclywith the circumference of the vcs scl, sothat the eihcient cooling ol' the liquid and consequent separation ofthe solids is a slow process.

The cooling; apparatus which we employ for carrying out our inventionconsists oi. a

battery, of cooling plates connected together in series or in. paralleland preferably in the form of hollow bodies into which the cooling fluid(water, brine, ammonia or the like) is introduced and through which itcirculates.

5 5 The paraifiu oil or the like which is conveyed into the spacesurrounding the cooling bodies is in this way divided into layers by thecool ng plates and the said layers may be made as thin as is desiredsorhat the cooling which is thus cll'ecrcd in the mass of the liquid isextremely ellicient and takes place rapidly. "he cooling surfaces, whichare formed by the sides of the cooling bodies :qucntly be easilyincreased by the enlai nient oi the diameter ol the vessel, arecrmtinuously scraped. by agitating or scraping inechanirnn so that thedeposits which are formed tl1ercon are rrj-niwireil, whereby goodcoiuliu'tion is insured and the sluice between the continuous coolingbodies may he made as small as possible thus insuring a rapid andclllcienl in the drawing W0 have illustrated e: amples of coolingappaatus constructed according to tlie'invention in whichz Figure 1 is alongitudinal section of the apparatus, the left hand portion of thefigure showing an arrangement.ivhercin each cooling; plate is suppliedwith resh cooling liquid and the right hand part of the figure anarrangeincnt in which the cooling plates are connected together inseries. 7 Fig. 2 is a transverse section of the pparatus on the lineA-A, Fig. l, and Fig. 3 illustrates an upright construction of coolingapparatus.

1 is the vessel for containing the paral'lin oil or the like to becooled and 2, 2 are the hollow bodies arranged Within the same and whichare framed of hollow ilat, conical or other bodies, the shape of .vhichis such that the sides or cooling surf thereof may be subjected to theaction oi "oping or agitatin; mechanism which simr iancously cl'l'ectsthe mixture of the li" d, The cooling lluid is conveyed into theinterior 0F the cooling bodies, for ilc, by means of pipes 3 and thesaid liuid is caused to circulate within the said bodies, tor instanceby means of bailles or the like 4, suitably superposed within the sameso that the iluid cannot pass out through the outlet 5 until it has beenpractically completely utilized. The arrangement may be such. that eachhollow body is separately supplied with fresh cool ing fluid (his: 1,left hand) or such that the cooling fluid leaving one plate is conveyedinto the next adjacent plate and so on (Fig. 1, right hand) and is onlydischarged after it ring the last plate; the parallel arrange-- men-tor" the plates can be combined with the series arrangement.

layer of paraffin oil (or Scrapers or stirrers 6 are provided on each 1side of each plate, the said scrapers being preferably keyed upon acommon shaft 7 which passes through the cooling bodies and which givesthe scrapers their motion. Dur ing the operation of the apparatus theycontinuously scrape the surfaces of the cooling l bodies so that thesubstance which is separated from the liquid and is deposited upon thesaid surfaces is continrumsly removed. l By this means the goodconduction of the cooling bodies is insured and, as deposits upon thecooling surfaces are prevented, the plates or cooling bodies may bearranged in near proximity to one another so that the the liquid) to be,cooled between two contiguous cooling tion being consequently rapid andefficient bodies is very thin, the resulting cooling ael l l to operateupon the eountercurrent principle l i For continuous working it isadvantageous l l i l and to this end we may arrange the cooling bodiesin series in such a manner that ihe cooling fluid after flowing throughone cooling plate is conveyed into the adjacent plate and 1 is only(llstfl'ittlgcd after its passage through i the last plate, the paraffinoil being conveyed into and caused to flow through the vessel in- 1closing the cooling bodies in the opposite direction to that in whichthe cooling fluid circulates.

Fig. 3 of the drawings shows anupright apparatus wherein the coolingbodies 2 are of a conical shape. The said bodies may be arranged as inthe preceding example either parallel to one another or in series or inparallel and series groups. The deposits adhering to the couicallyshaped cooling surfaces are reinrrved therefrom, as above described, bys-zcrapers 6 or stirring mechanism. The con- 1 ical form of the coolingbodies increases their acting surfaces and facilitates the removal ofthe deposit by the scrapers, it being observed that the convex side ofeach cooling body is uppermost.

What we claim as our invention, and desire to secure by Letters Patentis:-

1. In an apparatus for separating solids from liquids 1n which they aredissolved by cooling, the combination of the vessel containing theliquid to be cooled, a series of relatively'narrow circular hollowbodies arranged side by side in said vessel, an inlet and an outlet foreach of said bodies, a series of baffle plates arranged in said bodiesin substantially staggered relation whereby to form a tortuous or zigzag space through each hollow body, and a series of scrapers arranged toact upon substantially the whole outer surface of said hollow bodies,substantially as described. j

2. In an apparatus for separating solids from liquids in which they aredissolved by cooling, the combination of the vessel containing theliquid to be cooled, a series of circular hollow bodies through whichthe cooling medium circulates arranged parallel with each other and eachconical in cross section,

' said bodies being arranged in superposed disposition. with theirconvex sides uppermost, scrapers, and a common rotary spindle carryingsaid scrapers and extending through said hollow bodies, said scrapers toact upon the whole of the outer surfaces of said hollow bodies, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
